Li-ion Battery

Hitachi Li-ion batteries are 40% lighter than Ni-Cd and Ni-MH batteries. Selected Hitachi Li-ion batteries are fitted with a Multiple Protection Circuit that protects the battery and tool from overload, over-charge and over-discharge.

The Multiple Protection Circuit monitors each cell in the battery and will stop the tool instantly in the case of an overload.

This also ensures no damage to the battery during charging.

An over heating protection system is also fitted for further protection during use of the tool or charging the battery.
